Sources and sinks of acetone, methanol, and acetaldehyde in North Atlantic marine air

Little known about the occurrence of OVOCs (oxygenated VOCs) in the background atmosphere. Startling observation that they account for up to 85% of all non-methane hydrocarbons (NMHCs) measured in marine air conditions, and that they account for 80% of the loss of OH sink due to
all organic gases combined.

This is something quite unexpected and surprising: OVOCs have not been previously considered to be quite so important in clean marine air. OH is critical in determining the atmospheric lifetime of many gases, including climatically important gases such as methane.
